What can scratch a diamond?
talc
fluorite
another diamond
quartz
Which best describes scratchability?
If Item A can scratch Item B, then item A is harder than Item B.
If Item A can scratch item B, then Item B is harder than Item A.
Back scratchers should be long and have a scratchy point.
If Item A can scratch Item B, then neither item is harder than the other.
Which physical properties describe minerals? These properties can't be changed.
hardness
luster
color and streak
cleavage and fracture
size and shape
Are minerals the same as rocks?
No, rocks are composed of minerals and other components, such as sand.
Yes, minerals and rocks are the same.
No, only minerals exist, and some people just call them rocks.
No, rocks come from non-living things, and minerals come from living things.
Both minerals and rocks are made of inorganic (nonliving) components.
True
False
A mineral can be
a gas
a liquid
a solid
any state of matter
Can a mineral be composed of more than one type of atom?
Yes. Salt (NaCl) is an example. It is made from sodium (Na) chloride (Cl).
No. Only items with one type of atom can be a mineral.
No. Naturally occurring minerals are just a myth.
Yes. Minerals are manmade so they can be composed of anything.
Minerals can have multiple colors. How is the streak of a mineral determined?
The color is the streak, the color of the mineral's powder.
List all of the colors you see.
Name only the color that is the brightest.
Name only the color that is the darkest.
What is luster? Two correct answers.
could be pearly, metallic, or glassy
conduction of heat
another word for hardness
easily scratched
the way a mineral reflects light
How do we measure the hardness of a mineral?
Conduction, radiation, and convection
Mohs Hardness Scale
Talc
Quartz
Choose the 2 true statements.
Smooth, flat minerals break by cleavage.
Smooth, flat minerals break by fracture.
Uneven and rough minerals break by fracture.
Uneven and rough minerals break by cleavage.
The harder a mineral is, the less it can be scratched. Use the Mohs Hardness Scale to choose the true statement.
Talc can scratch quartz.
Topaz can scratch a diamond.
Topaz can scratch calcite.
Quartz can scratch corundum.
Which is an example of energy?
cold
heat
solid
matter
A force that can attract (pull closer) or repel (push away) objects that have a magnetic material like iron inside them
conduction
convection
thermal energy
magnetism
Which component must an item have to be magnetic?
iron
glass
plastic
any mineral
A measure of the ability of a material to transfer heat is called
thermal conductivity
hardness
luster
magnetism
Example of a thermal conductor
metal spoon
glass spoon
wooden spoon
butter
Electrical conductivity is the ability of electric current to flow through a material. Which 3 are examples of an electrical conductor?
water
glass
copper
any metal
wood
Choose the true statement.
Glass is a good conductor.
Glass is a good insulator.
Wood is a good conductor.
Copper is a good insulator.
BONUS LEVEL: Which image do you think would be the hardest on the Mohs Hardness Scale?
Top - More packed so harder than the bottom image to cut through
Bottom - Less packed so easier than the top image to cut through
BONUS LEVEL: Predict which would cleave and which would fracture. Look at molecule spacing. THIS IS EXTRA, NOT REQUIRED!
Diamond (left) - fracture because molecules are densely packed with no cleave line
Granite - cleave because molecules have a natural space that allows for an easy straight break (cleavage)
